SPRlNG-MOTOR.

SPECIFICATION forming part of Letters Patent No. 306,835, dated October 21, 1884.

Appliealimi tiled February H, 198-1. No moth-lo T cult whom it may CUILCU/Ib;

Be it ,known that 1, CHARLES L. Kinnna, a citizen ofthe UnitedStates, residing at New Brunswick. in the county of Middlesex and State of New Jersey, have invented certain new and useful Improvements in Spring-Motors, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, and tothe letters of reference marked thereon, which form part of this specification, in which- Figure l is a front view. of the entire machine; Fig. 2, an end view of the left-hand end of machine; Fig. 3, a top view of bearingframe removed from the machine and supporting the windingcylinder, winding-shaft, heve1-wheel, and stop-work mechanism. Fig. r is the spring-box B with the head removed, showing the spring attached by its outside end to spring-box B, and by its inner end to shaft (1, which passes through fusee and spring-box. Fig. 5 is an enlarged view of the mechanism by which 1 increase or diminish the tension of the spring. Fig. (5 is an enlarged view of center of bevel-wheel D, showing the friction- .clutch 0.

The legs or standards A A, with the table F, constitute the frame of the machine. In the frame is fixed the bearing-frame, Fig. 3, upon which are supported the winding-shafts m and 8. Through the frame below the bearing-frame passes the spring-shaft d. On the left-hand end of the frame, as shown in Fi 2, is hung the pendent lever F, with a foot rest at its lower end and carrying a pawl and pawl-catch.

The operation of winding the spring or storing the power is as follows: The crank is placed upon the crank-shaft either at m or at 9. If at m,it is turned to the right; if at 1;,it is turned to the left, thus winding the cord t from the fusee II upon the cylinder E, at the same time coiling up the spring in the spring-box, which is secured to the fusee. The machine is then ready to transmit the power thus stored up to either while the machine is running or at rest, he may do sowithout applying the crank by placing the foot upon the foot-rest rand swinging the pendent lever forward and back. The forward motion engages the pawl It? with the ratchet-wheel a, driving it forward, and by means of the shaft and two bevel wheels, 7) and u, rewinding the cord onto cylinder E.

To provide against overwinding I make fast to the end of cylinder E a worm, 11, which engages with the worm-wheel g, having as many teeth or spaces asthe number of turns \Villl'h I wish to ln ve given to the cylinder,\\'ith one tooth of double width. The thread on each end of the worm is cut off square. The wormwheel g allows the worm /i, and with it the oilinder E, to revolve freely until the squared end of the thread on the worm comes to the tooth of double width, when it is stopped, thus preventing damage by winding too far. To con- 7o trol the speed of the machine I make use of a brake, V, which may be held with any required pressure against the periphery of driving-wheel by thumb-screw 0; or the machine may he suddenly stopped by pressure of the 7 hand upon the end of the brake-lever, which projects beyond the table in-front of the machine.

Having thus set forth my invention, what I claim as new, and desire to secure by Let- 8o ters Patent of the United States, is

1. In amechanism for driving sewing-machines or other light machinery, a pendent lever adapted to be operated by the foot of the operator, and so arranged as to be capable of rotating a winding-cylinder, whereby the driving cord or belt may be wound upon said cyl inder, substantiallyas set forth.

2. In a mechanism for driving sewing-machines or other light machinery in a spring 0 winding apparatus, a wheel having teeth out in only a portion of its periphery, the remainder thereof being left blank, so as to allow only the desired number of revolutions of a connected worm, with a worm adapted to 5 revolve such wheel, together forming a stop or safety mechanism, substantially as set forth.

In a mechanism for drivmg sewing-machines or other light machinery, a frictionclutch adapted to hold the winding-cylinder I00 so that it will be actuated by the forward movement of the shalt, substantially as set forth.

4:. In a mechanism for driving sewing-machines or other light machinery, the combination of a pendent lever acting, by means of a pawl and ratchet, to revolve a winding-cylinder, a winding-shaft, a friction-cluteh connecting such shalt and cylinder, and a worm wheel tion 01" a d|'iving-s1,)ring having its outer end attached to a fusee or drum, which is secured upon a supporting-shal't. so as to revolve thereon, and its inner end fastened to such supporllug-shalt, a worm-wheel rigidly atlaelu-(i to such shaft, and a worm adapted to revolve such worm-wheel and shalt, substantially as set forth.

7. In a mechanism for driving sewing-mar chines or other light machinery, the combinationol" a \vinding'shat't adapted to be revolved by means of a crank, a winding-cylinder, a driving belt or cord, a fusee or drum adapted to receive the driving belt or cord, a frictionclutch capable of communicating the forward motion from the windingshal't to'the cylinder, and a pendent lever adapted to revolve the said windingcylinder, substantially as set forth.

In a mechanism for driving sewing-machines or other light machinery, the combination of a winding-shaft adapted to be revolved by means of a crank, and having attached to it a winding-cylinder, a driving belt or cord connected thereto,and also attached to a l'usee or drum adapted to receive such cord, a t'usee or drum attached to a spring-box (JOlltailllIlg a coil-spring so arranged as to revolve such drum or t'usee when allowed to unwind, a l'rie tion-rlutch capable of communicating the forward motion of the winding-shaft to the wind ing-cylinder, a bevel-wheel, pinion, and driving-wheel so arranged as to transmit power from thedriving-sprang, all arranged snbslalr tially as and for the purpose set forth.
